These phrases add humor and vivid description to speech. Some have regional variations.	Understanding these helps learners sound more natural, rather than relying on simple, literal vocabulary.
Context-Dependent Phrasal Verbs (‘Freak Out’)	The verb ‘to freak out’ has varied meanings (fear vs. anger) based entirely on the accompanying words and situation. Learners must pay attention to context to correctly interpret emotion.	It teaches that language is not always literal; meaning relies heavily on surrounding details.
Steer vs. Stir	‘Steer’ means to guide, direct, or avoid (e.g. guiding a car). ‘Stir’ means to mix a substance or create excitement/fussing. They are distinct words.	Correct usage is essential. Therefore, confusing them changes the entire meaning of the sentence.
Gross vs. Net Salary	‘Gross’ (bruto) refers to the total pre-tax salary or annual income. Meanwhile, ‘net’ (neto) refers to the actual take-home pay after national income taxes have been deducted.
